You will need to do the modification on your own if you're good at programming or hire a programmer to do that for you: http://www.oxwall.org/market/specialists
Also you can make a suggestion on uservoice: http://oxwall.uservoice.com/forums/13756-ideas-for-oxwall if it gets enough voices we'll consider implementing it.
Besides, you can make a post in the custom code modification probably some community member will assist you there.
